Archimedes, thank you!
Richard Woods you are ignoring facts. My post re break up may have been in Wakelam's book, but it is quoted from ORS.
As for aircraft blowing up, the wing usually burnt off or control was lost and the aircraft broke up, they did not blow up.
As for Lancaster crew losses, they are based on % numbers.
The Lancaster had hatches some 2 inches narrower than the Halifax , but I guess you will disagree with that fact as well!
